Optional garnishes: shredded lettuce, diced tomatoes, sliced black olives
Lightly spray a skillet with nonstick cooking spray. Saute onion and garlic in 1 tbs water over medium-high heat until water evaporates and vegetables begin to brown. Toss in scallions, chiles with liquid, tomatoes and salsa; mix well and turn off heat.
Add beans and boiling water to skillet. Mix well, scraping the veggie mixture up from the bottom of the skillet. Allow to stand until beans have absorbed liquid, about 10 minutes. Form into 6 patties.
Spray clean, heated skillet with nonstick cooking spray and add patties. Saute until patties are crisp on one side; turn and saute other side.
Garnish as desired.
